Allen-Bradley 1746-HSCE High-speed counter module Competitive prices

Product Description

The Allen-Bradley 1746-HSCE is a high-speed counter module for the SLC 500 family of programmable logic controllers (PLCs). It can be used to count pulses at frequencies up to 250 kHz, and it provides a variety of features for counting applications, including:

Four independent counter channels
Four output channels that can be used to generate pulses, control relays, or drive other devices
A variety of counting modes, including up/down counting, quadrature counting, and pulse width measurement
A built-in timer that can be used to generate delayed outputs or to measure the time between pulses

Product Parameters

Number of counter channels: 4
Number of output channels: 4
Maximum counting frequency: 250 kHz
Counting modes: Up/down counting, quadrature counting, pulse width measurement
Input voltage range: 10.8 to 30 V DC
Output voltage range: 10.8 to 30 V DC
Current consumption: 120 mA

Usage Methods

The Allen-Bradley 1746-HSCE can be used to count a variety of input signals, including:

Encoder pulses from motors, actuators, and other devices
Switch closures from limit switches, pushbuttons, and other sensors
Pulses from photoelectric sensors, proximity sensors, and other sensors

The counter channels can be configured to count pulses in a variety of modes, including:

Up/down counting: Counts pulses in either the up or down direction
Quadrature counting: Counts pulses from a quadrature encoder, which provides two pulse signals that are 90 degrees out of phase
Pulse width measurement: Measures the width of pulses in milliseconds

The output channels can be used to generate pulses, control relays, or drive other devices. For example, the output channels could be used to generate a pulse train to control a motor, or to turn on a relay to control a solenoid valve.

Product Advantages

The Allen-Bradley 1746-HSCE offers a number of advantages for counting applications, including:

High counting frequency: The 1746-HSCE can count pulses at frequencies up to 250 kHz, making it suitable for a wide range of applications.
Variety of counting modes: The 1746-HSCE provides a variety of counting modes, which makes it flexible enough to meet the needs of a wide range of applications.
Built-in timer: The built-in timer can be used to generate delayed outputs or to measure the time between pulses, which can simplify the design of control systems.
Rugged construction: The 1746-HSCE is designed to withstand the harsh environments of industrial applications.

Discontinuation

Rockwell Automation has announced that the Allen-Bradley 1746-HSCE will be discontinued and no longer available for sale as of September 30, 2024. Users of the 1746-HSCE should begin planning to migrate to a replacement product, such as the Allen-Bradley 1769-HSC module.
